is asingle trigger 7 and for the purpose of actuating the scars fromsaid single trigger I provide the following parts: Havmg pivotal support 8 upon the trigger plateis a bracket 9, a sear actuating bar 10 being? slidably supported by said bracket.

Said bracket is normally held pressed down against the trigger plate by a spring 11.

The slide 10 fits withinthe horizontal groove '11 of the bracket, the front end 12 slidably extending through the supporting block 13 forming partof the trigger plate, and the opposite end of the slide extending through the downwardly extending rear end 14 of the bracket, a spring 15 being interposed between the slide and the end 14 of the slide in a forward posigun. The bolt 19 is forced rearwardly to actuate the ar1n l6 and shove the slide to the position shown in Fig. 1. The slide is held in this position by the following described parts:

Secured pivotally at the right hand side of thereof is an outwardly and forwardly extending spring 20, said spring being formed at its free end with; a beveled hook nose 21. The slide is formed with a laterally projecting lug 22, which, whenthe slide is pushed backby the arm 16 willdepress the free end of the spring in passingover the nose 21, the free end of the spring thereafter springthe slide in the free en of the right hand sear 5.

a rearwardly swinging arm normally free from the latter and adapted to engage the same for movingthe slide rearwardly, and a bolt slidable on the breaking of the gun for swinging the last arm.

5. In a single trigger mechanism for double barrel guns, a block, a bracket pivoted at its forward end to the block, a sear actuator slidably supported by the bracket and provided with a forward extension projecting beyond the block, a rearwardly swinging arm normally free of the extension and adapted to engage the same for moving the actuator rearwardly. and a yieldable catch for engaging the slidable actuator same.

6, In a single trigger mechanism for double barrel guns, a pair of sears, an actuator therefor, a movable catch for holding the actuator in a set position to operate the first sear, and means engageable with the prevent setting of the actuator to actuate a sear.

7. In a single trigger mechanism for double barrel guns, a pair of sears, an actuator therefor, a spring latch 'adapted to engage the actuator for holding the same in a set position to operate a sear, and a lock movable to engage over the latch and hold the same depressed from the path of the actuator.

8. In a single trigger mechanism for double barrel guns, a pair of sears, an actuator therefor, having a projecting lug, a spring latch fixed at one end and having its other end of hook form to engage the lug and thereby hold the actuator from movement, the upper face of said hook end being beveled, and a lock slidably mounted and formed with an angular arm terminat ing in a hook to engage the beveled face of the latch for depressing the latter from normal position and interlocking with its hook end to retain the same inoperative.

9. In a single trigger mechanism for double barrel guns, the combination of two hammers, a sear for each hammer, a slide positioned between said sears, means for holding the slide in retracted position, a single trigger arranged in position to be actuated to release the slide from retracted position, means actuated by the slide as the same is released to operate the left hand sear, alug projecting outwardly from said slide in position to engage with and hold the left hand sear in normal position while the right hand sear is being actuated, said lug being thereafter engageable with the left hand sear to actuate the same through the medium of said single trigger.

10. In a single trigger mechanism for double barrel guns, a pair of sears, an interposed actuator having oppositely extending sear actuating lugs, means engaging one lug to hold the actuator set in a position for operating one sear, and means for engaging the first, means to lock the same inoperative relative to said specified sear.

11. In a single trigger mechanism for double barrel guns, a block, a sear on each side thereof, a bracket pivoted to the block and provided with a rearward extension having a downturned terminal and an upstanding slotted spring guide in advance of the latter, a leaf sprin secured on the extension rearwardly of t e guide and passing through the latter into the block for yieldingly holding the bracket down, an actuator slidably carried by the bracket for actuating the sears and provided with a rearwardly extending rod slidably received by the downturned terminal of the bracket extension, and a coiled spring encircling the rod between the downturned terminal and actuator body for urging the latter forwardly.

12. In a single trigger mechanism for double barrel guns, the combination of two hammers, a sear for each hammer, a slide positioned between said sears, a lug extending horizontally outward from the left hand sear and a perpendicular lug extending outwardly from said left hand sear and spaced from said horizontal lug, and a lu extending outwardly from the left han side of said slide, and adapted after said trigger is actuated to actuate the right hand sear, to first pass over said horizontal lug and hold the said left hand sear down and thereafter pass to impinging position against said perpendicular lug and upon said trigger being released to pass under said perpendicular for the purpose set forth.

In testimony whereof I aifix my signature in presence of two witnesses.
